NOTES:
. All capacities above the bold line are based on
structural strength of boom extension and do
not exceed % of tipping loads, in accordance
with SAE J .
. The ft luffing folding boom extension may be
used for single or double line lifting service. The
ft luffing folding boom extension may be
used for single line lifting service only.
WARNING: Lifting with the ft extension
base, with the ft extension fly either erected
or folded along side of extension base, is
strictly prohibited.
. WARNING: Operation of this machine with
heavier loads than the capacities listed is
strictly prohibited. Machine tipping with boom
extension occurs rapidly and without advance
warning.
. Boom angle is the angle above or below
horizontal of the longitudinal axis of the boom
base section after lifting rated load.
. Capacities listed are with outriggers properly
extended and vertical jacks set only.
. For main boom lengths less than
the boom extension erected, the rated loads
are determined by boom angle. Use only
the column which corresponds to the boom
extension length and offset for which the
machine is set up. For boom angles not shown,
use rating of the next lower boom angle.
. When lifting over the main boom nose with
ft or ft extension erected, the outriggers
must be fully extended or % extended
